Modal won’t appear on all pages

I inherited a WordPress site from another developer. He has a tabbed theme options page. The admin can select to have a modal pop up with a message. You can select which pages you want it to appear on. But right now it’s only working on the page that is first in the selected list:

So in this case, Home is the only place it’s appearing. The ACF field type is relationship, and it was supposedly working for awhile.

Here’s the json:

  {
        "key": "field_611e74a659c53",
        "label": "Specials Modal",
        "name": "",
        "type": "tab",
        "instructions": "",
        "required": 0,
        "conditional_logic": 0,
        "wrapper": {
            "width": "",
            "class": "",
            "id": ""
        },
        "placement": "top",
        "endpoint": 0
    },
    {
        "key": "field_611e74b659c54",
        "label": "Show/Hide",
        "name": "toggle_sm",
        "type": "true_false",
        "instructions": "Show or Hide the Button and Modal. By default it's hidden.",
        "required": 0,
        "conditional_logic": 0,
        "wrapper": {
            "width": "",
            "class": "",
            "id": ""
        },
        "message": "",
        "default_value": 0,
        "ui": 1,
        "ui_on_text": "Show",
        "ui_off_text": "Hide"
    },

Does anyone have any idea why the modal is only appearing for the first page in the list?

Here’s the php:

$display_ids = get_field('the_display_ids', 'options');
$id =  get_the_ID(); 
?>
@if ($display_ids != null)
  @if (get_field('toggle_sm', 'options') && in_array($id, $display_ids) === true)
    @include('specials-modal')
  @endif
@endif
